Electric retractable butterfly valve is a kind of valve widely used in industrial pipe system, it has a variety of advantages and characteristics. The following is some Chinese introduction of the electric telescopic butterfly valve:

Because of its thin design, light weight and small installation footprint, the electric butterfly valve usually has a low initial cost when compared to other valve designs.

Electric retractable butterfly valves are suitable for water, air, natural gas, oil and weakly corrosive fluids with a variety of drive modes including worm gear, electric, pneumatic and hydraulic.

Electric butterfly valve model SD341X, nominal diameter range from DN50 to DN2000mm, nominal pressure from PN0.6 to 1.6MPa.

The electric telescopic butterfly valve has the function of automatically compensating the thermal expansion and contraction caused by the temperature difference of the pipeline, which is easy to handle and load, and is suitable for regulating the flow and cutting off the fluid in the industrial pipelines of oil, chemical industry, electric power, paper making, water supply and municipal construction under the temperature of 120℃ and 1.6MPa below.

Electric telescopic butterfly valves are divided into three types: ordinary type, fixed limit type and extended type, of which the fixed limit type in addition to telescopic, but also has the function of limiting the telescopic part fixed and not moving, with multi-functional, wide range of application characteristics.

The characteristics of the electric retractable butterfly valve include the adjustable sealing parts to ensure reliable sealing performance; Unique structural design, light and flexible, labor-saving and fast; The expansion function can not only compensate for the thermal expansion and contraction of the pipe, but also facilitate the installation and replacement of the valve.

When installing the electric telescopic butterfly valve, it is necessary to pay attention to the valve must be placed horizontally, do not hit at will, and do not remove the support during operation; When installing, pull the valve to the installation length (i.e. the design length); If the pipe length exceeds the installation length of the expansion valve, please adjust the pipe spacing, do not forcibly stretch the butterfly valve, so as not to damage the valve; After the installation is complete, the temperature compensation can be carried out. After the installation of the pipeline, the limiting device is added at both ends of the support along the pipeline axis to prevent the expansion pipe from being pulled out.

The actuator of the electric telescopic butterfly valve has a variety of technical parameters, including three-phase AC motor, control line voltage, remote control voltage, ambient temperature, relative humidity, protection level and working system.
